Claims

[Claim for Utility Model Registration] In an automatic loom that weaves cloth by alternately distributing each of a large number of warp threads moving in parallel up and down, and pressing the weft threads passing between them in the direction of travel with a reed, A filler that presses down the fabric from above with a predetermined pressure with a protruding tip at a position several mm or more away from the final pressing position in the direction of movement, and the filler a sensor that detects, based on the movement of the filler, that the protruding end of the filler has sunk below the fabric by a predetermined length or more; and an operating point setting section that sets the amount of sinking of the filler at which the sensor starts detecting. A defect detector for looms, which is characterized by the following:
